Wende Absoluteregel an: Wenn

∣ u ∣ = a, a > 0

dann

u = a

u = - a

X - 4 = - \frac{10}{3} or X - 4 = \frac{10}{3}

X - 4 = - \frac{10}{3} or X - 4 = \frac{10}{3}

X = \frac{2}{3} or X = \frac{22}{3}

18 - 3 X^{1} = - 4

∣ x + 6 ∣ + 6 = 3 x^{3} x

- 3 ∣ 2 n + 8 ∣ + 7 = - 11

- 2 ∣ 2 x - 2 ∣ = 8

x^{2} - 2 x - 3 = 3 x - 3
